Get the air bag module scanned for codes. Could just be a "battery
power terminal 30 voltage too low" code (from disconnecting the battery).
Clear the code(s) with the same scan tool and see if the code(s) come back.
Not all OBDII code readers will rear Air Bag Faults. So you might
have to take it to a VW Shop.
